You are pushing a rubber crate against a concrete floor. The two surfaces have a static coefficient of friction of 0.61 and a kinetic coefficient of friction of 0.49. The floor is horizontal, and the crate has a mass of 25.0 kg, and is initially at rest. You are pushing with a horizontal force of 100 N. What is the magnitude of the force of friction in this case? Give your answer in units of N, to three significant figures.

You are pushing a rubber crate against a concrete floor. The two surfaces have a static coefficient of friction of 0.66 and a kinetic coefficient of friction of 0.52. The floor is horizontal, and the crate has a mass of 25.0 kg, and is initially at rest. You are pushing with a horizontal force of 85 N. What is the magnitude of the force of friction in this case? Give your answer in units of N, to three significant figures. You are pushing a wooden crate against a rubber floor. The two surfaces have a static coefficient of friction of 0.54 and a kinetic coefficient of friction of 0.42. The floor is horizontal, and the crate has a mass of 25.0 kg, and is initially at rest. You are pushing with a horizontal force of 135 N. What is the magnitude of the force of friction in this case? Give your answer in units of N, to three significant figures.

You are pushing a box, apply Fa = 90 N. The box's mass is 25 kg. The coefficients of friction are μs =0.60 and μk = 0.4. The box was stationary when you began pushing. Calculate the frictional force magnitude exerted on the box by the floor
